Bug Description:
  Problem encountered during annotation processing.

  The proxy returned from Declaration.getAnnotation() throws a
  ClassCastException when accessing a member/element whose type is an array.

java.lang.ClassCastException: [Ljava.lang.Object;
        at $Proxy0.value(Unknown Source)
        at MyProcessor.process(MyProcessor.java:20)
        at com.sun.mirror.util.CompositeAnnotationProcessor.process(CompositeAnn
otationProcessor.java:51)

        at com.sun.tools.apt.Main.main(Main.java:32)

Steps to Reproduce (be specific):
  - Unpack the attached jar.
  - recompile the *.java files with javac with tools.jar on the classpath
   (class files are included but you might want to recompile first)
  - run apt with the unpacked root on the classpath, and the source
    files as the source.

ON Windows
 U:>javac -cp "C:\Program Files\Java\jdk1.5.0\lib\tools.jar" *.java

 U:>apt -cp .;"C:\Program Files\Java\jdk1.5.0\lib\tools.jar" *.java

2 errors


  The source files MyAnn, MyAnnTarget and MyProcessor can be easily modified
  to get the same fault when the element type is int[]. It also occurs for
  booleans.
